Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

In the description of the present invention, "a plurality" means a plurality, e.g., two, three, four, etc., unless specifically limited otherwise.

In the description of the present invention, unless otherwise explicitly specified or limited, the terms "connected" and the like are to be construed broadly, e.g., as meaning fixedly attached, detachably attached, or integrally formed; can be mechanically connected, electrically connected or can communicate with each other; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.

Referring to fig. 1, a system for manufacturing an anti-counterfeit mark includes an inkjet device 301, an image capturing device 302, and a control device 303; the control device 303 can communicate with the inkjet device 301 and the image capturing device 302, wherein the control device 303 can be directly or indirectly connected with the inkjet device 301 and the image capturing device 302 by a wired connection, or can communicate with each other by a wireless connection.

The article to be provided with the security feature may be understood as the target article 304, and the printed security feature may be, for example, the security feature 305 shown in fig. 2.

The control device 303 may be understood as any device or combination of devices capable of implementing data processing, wherein an algorithm related to the fabrication of the anti-counterfeit mark may be configured, the control device 303 may be configured to execute the fabrication method described hereinafter and in the alternative, and further, the control device 303 may be understood as an execution body of the fabrication method, and in some examples, the fabrication system may also be used as the execution body.

The image capturing device 302 may be any device capable of capturing an image to obtain a reference image, and specifically, the image capturing device 302 may include an image capturing portion, and further include a lens and/or a microscope used in cooperation with the image capturing portion.

The image acquisition device 302 can be used for realizing the later amplified imaging of the patterns (standard anti-counterfeiting patterns and professional anti-counterfeiting patterns) with the first amplification factor and the second amplification factor.

The image capturing device 302 may adjust the lens and the microscope under the control of the control device 303, or may adjust the lens and the microscope manually, and the image capturing device 302 may also trigger image capturing (for example, capturing of a reference image) under the control of the control device 303.

In an image acquisition arrangement, magnification and imaging of the acquisition object may be achieved, in particular for the image acquisition arrangement of the first reference picture, the final magnification will depend on the magnification and imaging capabilities.

In addition, the image capturing device for capturing the first reference image and the image capturing device for capturing the second reference image may be different, the image capturing device 302 for capturing the first reference image may be an optical amplification sensing device (e.g., an electron microscope), which may include an optical device for implementing optical amplification and optical path transmission, and a photosensitive chip for implementing light sensing, and the image capturing device 302 for capturing the second reference image may be a mobile phone, a tablet computer, a camera, etc.

The inkjet device 301 may be any inkjet device capable of printing a three-dimensional image, such as a UV inkjet device (which may also be understood as a UV inkjet printer or a UV printer), without excluding other existing or innovative inkjet devices. The UV printer can adopt the piezoelectric type shower nozzle printing mode to implement and print, not with material surface direct contact, wherein, can rely on the inside piezoelectric effect of shower nozzle, spout the UV ink jet printing in the nozzle to the surface of material, the ultraviolet wave that utilizes the LED lamp to send carries out the solidification of UV ink, reaches and beats promptly and promptly dry the effect.

In the process of ink jet printing, in addition to producing a primary ink drop (i.e., a main ink drop), a smaller sized ink drop containing less colorant is also produced during the ejection of ink out of the nozzle: since such ink droplets follow the main ink droplets during flight, they are called satellite ink droplets similarly to satellites moving around planets. The cause of satellite drop generation varies with inkjet technology, and both continuous and drop-on-demand inkjet can occur; for example, the main ink droplets constitute the body of a character or graphic object, and the satellite ink droplets appear in the vicinity of the outline of the character or graphic object.

Among them, satellite drop formation is related to many factors, the most important of which include: technical parameters of the inkjet process, such as droplet generation and its speed of movement, pressure at which the droplet ejection is driven, etc.: printing principle parameters such as the speed and direction of movement of the print head; ink properties, viscosity, formulation, etc. all affect the formation and quantity of satellite droplets; an electronic control system of the inkjet printing apparatus; and so on. Meanwhile, the ink quality and stability are affected by the problems of ink physical indexes, ink supply system negative pressure, environmental temperature and the like. Furthermore, if the ink jet printed pattern is made large enough, the satellite ink droplets can be displayed in a form that is not controllable.

In order to utilize the uncontrollable property, the embodiment of the invention provides a method for manufacturing an anti-counterfeiting mark. The structure formed by UV printing may be a three-dimensional structure (i.e. at least one three-dimensional security pattern), and the generated texture has three-dimensional characteristics, and further, the security pattern may also carry three-dimensional characteristics. The three-dimensional features may also be fully considered in the acquisition of images of the security device and/or in the verification thereof.

Referring to fig. 3, the method for manufacturing the anti-counterfeit mark includes:

s11: controlling the UV ink-jet device to spray and print the anti-counterfeiting mark on the target object,

the anti-counterfeiting mark comprises a pattern area, and at least one three-dimensional anti-counterfeiting pattern is arranged in the pattern area;

s12: and imaging the anti-counterfeiting pattern on the target object as a reference image so as to use the reference image as a verification basis of the target object.

In the reference figure, the real size can be enlarged and imaged to the display size at a specified magnification. The specific magnification may be, for example, the first magnification and the second magnification mentioned later.

In the above scheme, the reference image of the anti-counterfeiting pattern is used as a verification basis, wherein the anti-counterfeiting mark is formed by adopting an ink-jet (for example, UV ink-jet) mode, and the ink-jet is jetted on a target article (which can be a commodity or a package, and can also be a medium on the commodity or the package), so that the anti-counterfeiting mark can be generated while the commodity is manufactured. Meanwhile, the reference image of the amplified anti-counterfeiting pattern is used as an anti-counterfeiting verification basis, the distribution condition of satellite ink drops except for the main ink drop in the amplified partial anti-counterfeiting pattern can be used as the anti-counterfeiting verification basis, wherein the distribution condition of the satellite ink drops is uncontrollable even if the same ink jet parameters are adopted, and the uniqueness and the irretrievable property of each reference image and each mark can be ensured based on the uncontrollable condition, so that the accuracy of the anti-counterfeiting verification can be effectively improved.

The anti-counterfeit mark may be, for example, as shown in fig. 7, wherein a pattern area 402 is illustrated in the anti-counterfeit mark, and in some schemes, the anti-counterfeit mark may be implemented by combining a two-dimensional code 401, a barcode, a character code (for example, a serial number), or other recognizable codes, that is: the anti-counterfeiting mark also comprises an identifiable code which is printed together with the professional anti-counterfeiting pattern and the standard anti-counterfeiting pattern by spraying, for example: the pattern area 402 may be distributed in the center of the two-dimensional code 401, or may be located at any other position. The pattern area 402 may be combined with the two-dimensional code 401 or may be separate.

In some embodiments, the recognizable code may be printed separately, for example, by the inkjet device 301, or by other devices, and further, the recognizable code may be a two-dimensional structure or a three-dimensional structure, where the recognizable code may not be printed together with the professional anti-counterfeit pattern or the standard anti-counterfeit pattern, and the recognizable code may be printed outside the pattern area 402 or inside the pattern area 402, for example, the recognizable code may be disposed separately from the pattern area 402, for example: the recognizable code may be on the bottom of the package and the pattern area 402 may be on the top of the package.

The recognizable code (such as the two-dimensional code 401, the bar code, the character code, and the like) can be used for jumping to a page during verification so as to enter a corresponding processing flow, can also realize extraction of corresponding information, can also be used as an extraction basis for patterns in the pattern area 402, and can be printed on a target article through inkjet printing with the recognizable code and the pattern area 402 during manufacturing.

In one embodiment, the at least one security device comprises a professional security device, which may be a professional security device 4022 as shown in fig. 8; in some examples, the at least one security device may only include a professional security device, and in other examples, as shown in fig. 8, the at least one security device may include both a professional security device and a standard security device 4021; in other examples, the at least one security device may also include other devices.

The position of the professional anti-counterfeiting pattern can be determined according to the boundary shape of the pattern area, and then the effect of positioning and extracting the professional anti-counterfeiting pattern based on the boundary shape can be achieved.

For example, the professional anti-counterfeiting pattern can be disposed adjacent to a boundary, in the illustrated example, the boundary of the pattern area 402 can be a polygon, wherein the professional anti-counterfeiting pattern 4022 is distributed at one corner of the polygon, and in other examples, the professional anti-counterfeiting pattern can be adjacent to a midpoint of one side of the polygon, a center of the polygon, and the like.

In the case that the boundary of the pattern area 402 is a polygon, the standard security pattern 4021 therein is a cross, and the center of the cross coincides with the center of the polygon. In other examples, the standard security pattern may also be polygonal or in other shapes, wherein the standard security pattern may be adapted to be combined with the professional security pattern or may be separate; in the example shown in fig. 8, the pattern area 402 may be rectangular (specifically, may be square), and a blank area may be further disposed inside the boundary of the pattern area 402, and the blank area may be, for example, circular and distributed at other corners of the polygon, and other areas inside the boundary of the pattern area 402 may be sprayed with black ink.

In one embodiment, if the at least one security pattern includes a professional security pattern, referring to fig. 10, step S12 may include:

s121: and imaging the professional anti-counterfeiting pattern on the target object into a first reference image so as to use the first reference image as a verification basis of the target object.

By a professional security device is understood that the device is not reproducible by counterfeiters, because the device is not as fine as possible when enlarged to the current level.

Wherein the specified magnification factor corresponding to the first reference map is a first magnification factor configured to: the method can enlarge and image a real size smaller than or equal to a printing limit size into a display size capable of being resolved; the printing limit size refers to the minimum size which can be printed under the highest printing precision of at least part of the designated printers; on the basis of the satellite ink droplets, at least part of the satellite ink droplets can be displayed individually after the amplification at the first magnification.

The designated at least part of the printers may be all printers (e.g., commercial printers) currently on the market or mainstream printers (e.g., commercial printers), and in a specific example, the designated at least part of the printers may be: may be used in at least part of a printer as the ink jet device.

If 0.001mm (i.e. 1 μm) is used as a printing limit size, and the target of the professional anti-counterfeiting pattern enlargement and collection can be, for example, enlarging and imaging a 0.001mm by 0.001mm area to a clearly distinguishable degree, for example, if 10 by 10 pixels are used for displaying, enlarging 0.001mm to 10 times of the pixel size is needed. The printing limit size of 1 μm may be understood as one size according to the current printing technology level, and in other examples, other sizes may be selected at different times.

The size (e.g., real size, display size) may be, for example, a length size, an area size, or the like.

For example: assuming the highest resolution of an inkjet printer is 2880DPI, the diameter of the printed ink drop is about 0.01mm to 10 μm.

The ideal purpose is to see the details of 1 μm. If 0.2mm is a size that can be distinguished by the naked eye (i.e., the target size is 0.2mm), 0.2mm/1 μm is required for enlargement from 1 μm to 0.2mm by 200 times. Namely: the first magnification is 10X 1/X2-200;

if the image acquisition equipment for acquiring the first reference image is optical amplification sensing equipment;

then: the first magnification is determined according to the optical magnification of the optical magnification sensing equipment and the pixel size of a light sensing chip in the optical magnification sensing equipment.

For example, based on a real size of 1 μm, there are:

if the pixel size of the photosensitive chip is 10um, the display size as the magnification target is 100um, and further needs to be magnified by 100 times (i.e. the first magnification is 100 times).

If the pixel size of the photosensitive chip is 3.4um, the display size as the magnification target is 34um, and then 34 times of magnification is required (i.e. the first magnification is 34 times).

Therefore, based on the optical magnification (which can be embodied as optical magnification) and the pixel size of the sensing chip, the imaging result can be ensured to image the real size which is less than or equal to the printing limit size into the display size which can be resolved.

The anti-counterfeiting effect of the professional anti-counterfeiting pattern can be embodied in the following aspects:

since the above scheme enlarges and images a real size smaller than or equal to the printing limit size to a display size that can be resolved. On the 1um scale, normally printed drops (typically tens of microns in diameter), with the edges and three-dimensional height variations formed by spreading of the drop from the drop state onto the substrate, can be distinguished. Furthermore, in the first reference image, various uncontrollable factors (such as satellite ink droplets) can be effectively reflected, and if copying and counterfeiting are required, high-precision color three-dimensional scanning (with a precision at least one order of magnitude higher, for example, at least 0.1um is required), and then a high-precision printer (with a precision at least one order of magnitude higher, for example, at least 0.1um is required, for the printer, the required resolution is 25.4/0.0001 — 254, 000dpi, which is not achieved by all current printers, so that the anti-counterfeiting texture cannot be copied by the high-precision printer) is adopted, so that the above scheme can effectively improve the difficulty of copying.

Secondly, in the case of satellite ink droplets, the satellite ink droplets are uncontrollable, so that a counterfeiter generates new satellite ink droplets during printing, which also increases the difficulty of copying.

In addition, the overlapping effect caused by the staggered overlapping of the ink drops in the printing process and the three-dimensional effect generated by the stacking of the UV ink drops can further improve the copying difficulty.

In one embodiment, if the at least one security device includes a standard security device, referring to fig. 10, step S12 may include:

s122: and imaging the standard anti-counterfeiting pattern on the target object into a second reference image so as to use the second reference image as a verification basis of the target object.

The specified magnification factor corresponding to the second reference picture is a second magnification factor, which is smaller than 15 times, for example, 6-10 times (the magnification factor of the current mainstream mobile phone is about 10 times, so that the ratio can be helpful for matching the mobile terminal of this type). Specifically, the second magnification factor may be realized by using a lens, or may be realized by using a combination of a lens and a lens, or may be realized by using a focal length change of the image capturing unit itself.

The second magnification may match a magnification capability of at least a portion of a mobile terminal used to authenticate the target item; correspondingly, the first magnification is higher than the magnified imaging capability of the mobile terminal on the real size (which can be understood as the maximum magnification on the real size when imaging), that is: the first magnification is higher than the second magnification. Further, in a specific example, when the verification of the standard anti-counterfeit pattern is implemented, the verification may be implemented by using only a mobile terminal, and when the verification of the professional anti-counterfeit pattern is implemented, the verification may be performed by combining the mobile terminal with another device (for example, a microscope) or using an apparatus such as an electron microscope.

The second magnification may be less than 20 times, corresponding to a value where the first magnification is greater than or equal to 20 times.

Therefore, the second magnification factor can be achieved by mainly selecting the mainstream mobile phone without external equipment, the convenience is mainly considered, and the second magnification factor can be 6-10 times specifically.

The anti-counterfeiting effect of the standard anti-counterfeiting mark is realized by controlling different textures generated each time, and the satellite ink drops are detected as a part of the textures, so that the difficulty of counterfeiting can be increased. Counterfeiters can achieve this by scanning the texture and then printing it, but because of the high resolution, high precision scanning and reprinting is very costly, and the high cost prevents the anti-counterfeiting effect achieved by copying.

Furthermore, at this resolution, different textures are mainly detected, and other features (e.g., satellite droplets) cannot be guaranteed to be detected. The standard anti-counterfeiting method is mainly applied as a convenient anti-counterfeiting mode.

In one embodiment, step S11 may include:

s111: determining a corresponding specific pattern aiming at an anti-counterfeiting area where the anti-counterfeiting pattern is located in the pattern area; the corresponding specific pattern represents a plurality of position points in the anti-counterfeiting area and the color of each position;

s112: and jetting corresponding colors at each position point to form blocks at the position points and the vicinity thereof.

The position point can be understood as a position point needing controlled ink ejection, for example, the position point can be characterized by coordinates in a two-dimensional coordinate system, when an ink ejection device is controlled to eject ink, the ink ejection device can be controlled to eject ink at the position point to form a main ink point, meanwhile, ink can be ejected around the position point to form a satellite ink point, in addition, the shape of the position point can be correspondingly adjusted based on the action, the forming principle, the environment and the like of other inks, and finally, the block mentioned herein can be formed. It can be the different block in each shape in the standard anti-counterfeiting pattern in figure 8, or the different block formed by three or three groups of position points in the professional anti-counterfeiting pattern in figure 9.

In a further aspect, step S1111 may include:

s1111: randomly determining the plurality of location points within the anti-counterfeiting area;

s1112: randomly dividing the anti-counterfeiting area to obtain a plurality of sub-areas;

s1113: and randomly distributing color or texture to each sub-area, and determining the color of each position point in each sub-area according to the distribution result.

Because the area, the texture and the color are randomly determined, the non-replicability of the standard anti-counterfeiting pattern can be guaranteed, and the accuracy of anti-counterfeiting verification can be effectively improved based on the standard anti-counterfeiting pattern.

In a specific scheme, referring to fig. 6, if the anti-counterfeit pattern includes a professional anti-counterfeit pattern, and the area where the professional anti-counterfeit pattern is located in the pattern area is a professional anti-counterfeit area, then:

step S1111 may include: s11111: randomly determining a plurality of first position points in the professional anti-counterfeiting area;

step S1112 may include: s11121: randomly dividing the professional anti-counterfeiting area to obtain a plurality of first sub-areas;

step S1113 may include: s11131: and randomly distributing color or texture to each first sub-area, and determining the first color of each first position point in each first sub-area according to the distribution result.

Referring to fig. 6, if the anti-counterfeit pattern includes a standard anti-counterfeit pattern, and the area where the standard anti-counterfeit pattern is located in the pattern area is a standard anti-counterfeit area, then:

step S1111 may include: s11112: randomly determining a plurality of second position points in the standard anti-counterfeiting area;

step S1112 may include: s11122: randomly dividing the standard anti-counterfeiting area to obtain a plurality of second sub-areas;

step S1113 may include: s11132: and randomly distributing color or texture to each second sub-area, and determining the second color of each second position point in each second sub-area according to the distribution result.

Wherein, the number of the first position points is less than 5, for example, three.

In a specific example of step S111, the specific pattern may be determined based on a corresponding generation algorithm, and further, the process (applicable to the professional anti-counterfeiting pattern, the professional anti-counterfeiting area, and also applicable to the standard anti-counterfeiting pattern, and the standard anti-counterfeiting area) may be, for example:

randomly selecting a plurality of position points in the anti-counterfeiting area (corresponding to step S1111); randomly growing an area outwards by taking each position point as a center, and dividing the anti-counterfeiting area into a plurality of small blocks (corresponding to step S1112); the respective patches are filled with different colors or textures (corresponding to step S1113).

In one embodiment, the method for controlling the UV inkjet device to jet print the anti-counterfeit mark on the target object further includes:

printing ink (e.g., white ink, other colors of ink may be used) on the pattern areas to form ink bumps from a stack of white ink such that; when the ink corresponding to each position point is jetted, at least part of the color ink is jetted to the ink bulges.

For example: white ink bulges can be formed by piling up white ink in UV ink, then a UV ink-jet device (namely a UV printer) identifies a place needing to be bulged in a pattern through a spot color channel, 1 layer, 2 layers or even a plurality of layers of white ink are piled up according to the requirements of a printing process, then CMYK ink (namely color ink) in the UV ink is sprayed and printed on the white ink, and finally gloss oil is covered on the white ink to form a relief feeling.

It can be seen that the reference map formed may be a two-dimensional map; the later figure to be verified may be a two-dimensional figure. The two-dimensional map may be a single two-dimensional map or a plurality of two-dimensional maps under different light conditions (such as brightness, light source position, etc.).

In the two-dimensional image, a three-dimensional feature of the anti-counterfeiting mark can be carried, and when the three-dimensional feature is collected to form a reference image and/or a to-be-checked image, the three-dimensional feature can be obtained by adopting an optical method, such as: local vertexes of the three-dimensional structure can be displayed as highlight points in the image, and the size and the position of a high-brightness area of the three-dimensional graph can be changed by adopting different light ray intensities and light ray angles, so that three-dimensional characteristics can be embodied.

In addition, when the reference image and the image to be checked are collected, the light irradiating the article can be controlled, such as the light intensity and the light direction; for example, if the light source includes a plurality of light sources at different positions, the light applied to the article is controlled by turning on the light sources at the different positions. Furthermore, the manufacturing system and the verification system may each include one or more light sources, and the light sources may be connected to the corresponding devices (e.g., the control device 303 and the verification terminal 401) to be controlled, or the light sources may be manually controlled.

In order to verify the article with the anti-counterfeiting mark manufactured by the manufacturing method, the anti-counterfeiting mark verifying method is provided, is applied to a verifying terminal, and can be used for verifying the anti-counterfeiting mark manufactured by the manufacturing method related to the first aspect and the optional aspects of the first aspect.

To implement the authentication method, please refer to fig. 11, which provides an authentication system for an anti-counterfeit mark, which may include an authentication terminal 401, where an article to be authenticated can be understood as an article 403 to be authenticated, and the anti-counterfeit mark to be authenticated may be, for example, the anti-counterfeit mark 402 shown in fig. 11.

In one embodiment, the authentication system for the anti-counterfeit mark may further include at least one light source;

And further, the light irradiating the anti-counterfeiting pattern is controlled by turning on the light sources at different positions and/or controlling the brightness.

In one embodiment, the authentication system for the anti-counterfeit mark may further include an optical amplifying device; the anti-counterfeiting pattern can be directly or indirectly imaged into the image to be checked after being amplified by the optical amplification equipment. The optical magnification device may be, for example, a microscope, a lens, or the like.

In a further example, the verification system may further include a microscope and/or lens that may be mounted to the verification terminal 401 (or used in combination with the verification terminal 401) to achieve the third magnification and the fourth magnification based on the microscope and/or lens.

In an example, the fourth magnification may be achieved based on a camera of the verification terminal, or the third magnification may be achieved based on a combination of the camera of the verification terminal and a lens (or a microscope).

The authentication terminal may be any terminal such as a mobile phone, a tablet computer, a computer, etc., which can be used to implement the authentication method referred to hereinafter. The authentication terminal may be a mobile terminal having mobile communication capabilities.

Referring to fig. 12, the verification method includes:

s21: imaging the anti-counterfeiting pattern on the article to be inspected into an image to be inspected;

in the graph to be checked, the real size can be amplified by a set amplification factor and imaged as a display size, and the set amplification factor is matched with the specified amplification factor;

s22: and comparing the image to be verified with the reference image to verify the authenticity of the article to be verified.

The set magnification factor comprises a third magnification factor corresponding to the professional anti-counterfeiting pattern and the professional anti-counterfeiting area, and also comprises a fourth magnification factor corresponding to the standard range pattern and the standard anti-counterfeiting area. The matching relationship between the set magnification and the designated magnification may be, for example, the same or similar (the difference or the ratio is smaller than a certain matching threshold), for example: the first magnification and the third magnification may be matched, the difference or ratio of the two may be less than a certain first matching threshold, or: the first magnification is equal to the third magnification; for another example: the second magnification and the fourth magnification may be matched, and the difference or ratio between the two may be smaller than a certain second matching threshold, or: the second magnification being equal to the fourth magnification

Further, if the verification of the professional anti-counterfeiting pattern is triggered, the following steps are performed:

step S21 may include: s211: imaging the professional anti-counterfeiting pattern on the article to be inspected into a first image to be inspected;

step S22 may include: s221: comparing the first to-be-verified image with a first reference image corresponding to the professional anti-counterfeiting pattern, and verifying the authenticity of the to-be-verified article;

step S21 may include: s212: imaging the standard anti-counterfeiting pattern on the article to be inspected into a second image to be inspected;

step S22 may include: s222: and comparing the first to-be-verified image with a second reference image corresponding to the standard anti-counterfeiting pattern, and verifying the authenticity of the to-be-verified article.

The comparison and verification process in step S22 (and steps S212 and S222 thereof) may be performed by comparing the overall similarity between the to-be-verified graph and the reference graph or the similarity of a specific region. For example: if the similarity is higher than the specified similarity threshold, determining that the similarity is matched with the specified similarity threshold, and determining that the article to be checked is true; if the similarity is lower than the similarity threshold, the article to be checked is determined to be fake.

Specifically, referring to fig. 13, the method for verifying the anti-counterfeit mark may further include:

s23: scanning the two-dimensional code in the anti-counterfeiting mark on the article to be checked, and entering a verification selection interface;

s24: and responding to the selection operation of the verification selection interface, and triggering to enter the verification of the professional anti-counterfeiting pattern or the verification of the standard anti-counterfeiting pattern.

Further, the following steps may be performed:

s25: whether the special anti-counterfeiting pattern is triggered or not is verified;

s26: whether the anti-counterfeiting pattern is triggered to be verified or not;

if the determination of step S25 is yes, step S211 can be performed;

if the determination of step S26 is yes, step S212 may be performed.

The verification selection interface can be, for example, as shown in fig. 14, a click on "standard anti-counterfeiting" can be understood as triggering the verification of the standard anti-counterfeiting pattern, and a click on "professional anti-counterfeiting" can be understood as triggering the verification of the professional anti-counterfeiting pattern. Clicking the 'trace back' can call up relevant information based on the two-dimension code.

In a specific example, the process of verifying the standard security pattern may be, for example:

1. opening an anti-counterfeiting identification APP;

2. shooting the two-dimensional code in the anti-counterfeiting mark by using a camera of a mobile phone (namely a verification terminal);

3. enter an interface such as that shown in FIG. 14, click "Standard forgery prevention"; the special anti-counterfeiting pattern is triggered to enter the verification of the special anti-counterfeiting pattern;

4. the mobile phone (namely the verification terminal) automatically enters an amplification mode, namely is triggered to enter the verification of the standard anti-counterfeiting pattern; the amplification factor is 6-10 times according to different mobile phones (namely verification terminals);

5. adjusting the standard anti-counterfeiting area to be positioned in the middle of the image viewing frame, keeping the standard anti-counterfeiting area as stable as possible, and then pressing an 'identification' key; wherein the viewed image may be as shown in fig. 14, for example;

6. if the display result is 'the product is a genuine product', the standard anti-counterfeiting area is verified to be in accordance with. If the display result is that the product is probably a fake product, the image is blurred due to shaking during photographing, and the product is verified again and confirmed.

Furthermore, the anti-counterfeiting effect of the standard anti-counterfeiting method is on the same level with the effect of the current main anti-counterfeiting method based on the mobile phone camera. The counterfeiter needs to scan the standard anti-counterfeiting area with high precision and then print the same pattern by using the same process parameters.

In a specific example, the process of verifying the professional anti-counterfeiting pattern can be, for example:

1. accessing a mobile phone (namely an authentication terminal) to an external microscope (for example, in an OTG/wifi mode);

2. opening an anti-counterfeiting identification APP;

3. shooting the two-dimensional code by using a camera of a mobile phone (namely, a verification terminal);

4. entering an identification interface (which can be understood by referring to corresponding controls in the interfaces shown in fig. 14 and 16), and clicking 'professional anti-counterfeiting';

5. the mobile phone (namely the verification terminal) automatically enters a microscopic mode; the special anti-counterfeiting pattern is triggered to enter the verification of the special anti-counterfeiting pattern;

6. placing the microscope on the security image, adjusting the position until the professional security area is in the middle of the image, and then pressing an "identify" button, the interface of which may be, for example, as shown in fig. 16; the first image to be examined acquired may be, for example, as shown in fig. 15;

7. if the display result is 'the product is a genuine product', the standard anti-counterfeiting area is verified to be in accordance with. If the display result is that the product is probably a fake product, the image is blurred due to shaking during photographing, and all the images need to be verified again and then confirmed again.

The professional anti-counterfeiting area is observed in a microscopic mode, the anti-counterfeiting area has obvious three-dimensional characteristics (for example, all frame areas are black, and white display is caused by reflection of prominent points to light), meanwhile, in the printing process, due to the existence of satellite ink drops, a plurality of small dots which are randomly distributed are generated in the pattern, and even if the same process is adopted, the small dots cannot be reproduced, so that a counterfeiter cannot generate the same three-dimensional pattern even if the high-precision scanning is adopted and then the printing is carried out.

Therefore, in the specific example of the present invention, in the generation and identification processes of the standard anti-counterfeiting area and the standard range pattern, the shape of the area can be generated in the standard anti-counterfeiting area by using a random algorithm, and the pattern in the standard anti-counterfeiting area can be generated by filling the area with different colors. Then, the image is amplified by a camera of the mobile phone and then compared with the stored standard anti-counterfeiting image to identify the authenticity of the commodity.

In the specific example of the invention, in the generation and identification process of the professional anti-counterfeiting area and the professional anti-counterfeiting pattern, the professional anti-counterfeiting texture can be randomly generated in the specific professional anti-counterfeiting area, and the principle is that an uncontrollable image generated by ink drop splashing in the ink-jet printing process is utilized. This image is substantially the same as the design target image, but at the same time overlaps the pixels of uncontrolled drop generation. Then, a special area in the anti-counterfeiting texture can be amplified by adopting an external mobile phone (OTG or wireless connection) microscope, and the image of the special area is compared with the stored professional anti-counterfeiting image so as to identify the authenticity of the commodity.

THE OTG can be understood as ON THEE GO, and THE OTG (also can be understood as OTG equipment) can have THE function of connecting external equipment.

In a specific example, the microscope can be used as a professional identification tool, and then can be directly inserted into a Type-C/Micro interface of a mobile phone (e.g., an authentication terminal).

Referring to fig. 17 in combination with fig. 11 and fig. 2, an anti-counterfeit processing system is provided, which includes: the above fabricating system of the anti-counterfeit mark, the verifying system of the anti-counterfeit mark according to the fourth aspect, and the data server 500 for storing the reference map.

In some embodiments, the anti-counterfeit processing system may further include a backend server 600, and further, when performing the verification, the verification terminal 401 may perform the process of step S22 at the verification terminal 401, or request the backend server 600 to perform the process.

Further, step S22 may specifically be: sending the to-be-checked image and the reference image to a background server, requesting the background server to compare the to-be-checked image with the reference image, verifying the authenticity of the to-be-checked article and acquiring a verification result; or: the background server calls the reference image from the data server 500, and compares the reference image with the image to be verified based on the called reference image and the image to be verified, so as to verify the authenticity of the article to be verified.

No matter how the authentication terminal operates, as long as the comparison and authentication are realized, the scope of the embodiments of the present invention is not deviated.
